Our Mission

The mission of PREP, a Threshold Foundation Funding Circle, is to support organizations in the space of research, education and policy reform for the safe and legal use of psychedelics as tools for medical and spiritual benefit.

Our Strategy and Focus

By regularly engaging with the Psychedelic community through conferences, lectures, fundraising and social engagements, our members have their ear to the ground in terms of the latest pulse in the Psychedelic movement. By being vital members of the community, we present as a united front for progressive philanthropy in psychospiritual mental health and eco-consciousness.
